GATE.

EBPECIPIGATIQN forming part of Letters Patent No. 341,645, dated May 11, 1886.

Application filed-February 8, 1886. Serial No. 191,i65, (No model.)

To all whom it may concern:

Be it known that I, THOMAS W. EDRING- TON, of Patriot, in the county of Switzerland and State of Indiana, have invented a new and Improved Gate, of which the following is a full, clear, and exact description.

The object of my invention is to provide a gate which may be opened by parties desiring to pass along the way blocked thereby without the necessity of descending from the vehicle in which they are riding; and to this end the invention consists of certain constructions to be hereinafter described, and specifically pointed out in the claim. v

Reference is to be had to the accompanying drawing, forming a part of this specification, in which my improved form of gate is shown as partly open.

In setting up such a gate as is illustrated in the drawing above referred to, I provide a heavy post, A, upon one face of which there is secured a deeply-grooved roller, B, in the groove of which rests a supporting-rail, G, fixed upon one side of the upper rail of the gate D, and the lower rail of said gate runs between friction rollers or balls, E, on an arm, A, projecting from said post A. Upon the same side of one of the lower rails of the gate there is an outwardly-extending guiding'rail, E, which runs in the peripheral grooves of two rollers, F and F, that are carried by the fence-post G, the rail E being rigidly braced by a diagonal bar, H. A doublesheaved pulley, I, is mounted upon the top of the post A, and just below this pulleyI there is fixed a bar, J, which extends at right angles to the gate and projects for a suitable distance from either side of the post A. Sheaves K K, provided with crank-arms L L, are pivoted at each end of the bar J, and about these sheaves there is passed an endless chain or rope, M, the upper strand ofwhich encircles the lower section of the double-sheaved pulley I, the lower strand being supported by a sheave, N, as shown. About the upper section of the double sheaved pulley I there is passed a chain or rope, O, the ends of which are secured to the tops of the upwardly-extending posts P and Q of the gate D. A spring-catch, R, is fixed, as shown, to one of the gate-bars, in position to-engage with the latch S upon the post T.

The operation is as follows: \Vhen the gate is closed, the catch R will be in engagement with the latch S, and consequently, before the gate can be drawn back in the direction of the arrow, the parts named must be disen' gaged; but this disengagement is brought about by turning one of the crank-arms L L so as to move the chain or cord M in the direction of the arrow' shown in connection therewith, for this movement of the chain M will rotate the double-sheaved pulley I and subject thelength of cord 0, extending to the post 1?, to a considerable strain, which will tend to raise the forward end of the gate and disconnect S and R. A continued rotation of either of the sheaves K will move the gate back in the direction of the arrow, and thus permit the free passage of the vehicle.

I am aware that a sliding gate has had a rope secured at both ends to the upper corners of the gate and passed around a pulley on a transverse shaft above, the shaft having its ends cranked in some instances, and connected in others with separate crank-shafts by beveled gearing; also, that a sliding gate has had its end bars extended above the top rail and connected by a rope that passes around a drum in opposite directions and through apertures in guide-boards, loops being formed in the rope after passing through the guide boards, and weights being pro vided on the looped parts. I am also aware that the lower rail of the gate has been extended to form a guide-rail, a diagonal brace extending from said extension to the vertical bar at the end of the gate, and I do not claim the same as of my invention.

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is

The combination, with a sliding gate having vertical posts 1 Q at its ends, extending above the gate, of the post A at the rear end of the gate, the cross-bar J at the upper end of post A, transverse to the gate, the double horizontally-revolving pulley I on top of the post A, erank-pulleys K L at opposite ends of the bar J, the rope 0, connected to the posts 1 Q at its ends and passed around one section of the pulley I, and the endless rope M,passed around the pulleys K K and around the other section of the pulley I, substantially as set forth.
